The effects of two types of agricultural practice: (1) Variable Rate Application (VRA) and (2) uniform (UNI) N dose on selected chemical properties of soil were compared in a field fertilization experiment. Nitrogen, in doses 60 or 80 kgN.ha-1 (UNI), and 55-105 kgN.ha-1 (VRA) was applied to soil farmed with winter wheat (Triticum aestivum L.). The research was conducted in the 2012/2013 growing season in Poland on 22 ha of production fields located in the Imielin countryside (central Poland). The soil samples were taken from three depths: 0.0-0.3 m, 0.3-0.6 m, and 0.6-0.9 m, and the pH, HAC, TEB, CEC, and BS were determined. The application of the nitrogen fertilizer in the two types of agricultural practice - Variable Rate Application (VRA) and uniform (UNI) N dose modified the basic physical and chemical properties of soil. The highest values of pH and hydrolytic acidity were observed at the soil depth of 0.6-0.9 m after the first rate of nitrogen fertilizer was applied. Cation exchange capacity of soils collected after uniform nitrogen rates were characterized by values decreasing with the increasing depth of the soil profile. |
